Your financial data privacy is our top priority. We do not transmit, store, or save any of the salary or tax data you enter into our calculator.
All calculations are performed strictly on the "client-side" (in your web browser) using JavaScript. Your inputs (salary, tax code, pension details) never leave your device and are wiped as soon as you refresh the page or close the tab.
We use local storage (a modern alternative to cookies) for strictly functional purposes:
To keep this tool free, we use Google AdSense to display advertisements. Google and its partners may use cookies to serve ads based on your prior visits to this website or other websites.
Under the General Data Protection Regulation (GDPR) and UK Data Protection Act 2018, you have rights regarding your personal data. However, because we do not collect or store any personal identification data (PII) or financial data on our servers, we hold no data to request, delete, or modify.
For data processed by our advertising partners (Google), please refer to their respective privacy policies.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
